Advantages of using HTS in Accelerator Magnets
- HTS has a potential to produce very high field magnets
- HTS based magnets can work at elevated temperatures
- a rise in temperature from, e.g., decay particles can be tolerated
- the operating temperature does not have to be controlled precisely
- HTS based magnets don’t appear to quench in the normal sense
- Weak spots don’t limit the magnet performance, instead the local temperature rises a bit (major difference from LTS magnets).
It becomes a question of heat load rather than a weak spot limiting the performance of the entire magnet
As compared to LTS, the critical current density (Jc ) falls slowly
- as a function of field
- as a function of temperature
